CHAPTER 1

Making Working Discs.

This chapter discusses how to make discs to use from day to day, and introduces some facilities of CP/M and its Utility programs.

Subjects covered are:

•Making a backup Master System/Utilites disc

•Constructing a Working Systems/Utility disc.

•Operating with a BASIC only disc.

•Installing a Turnkey AMSTRAD BASIC application.

•Installing a Turnkey CP/M application.

The foundation course has described how to format a blank system disc, which you can use for BASIC and games as well as CP/M, and how to make exact copies of discs with the DISCCOPY (one drive) or COPYDISC (two drive) programs. This chapter considers how to make discs with the programs that you want on them.

1.1 Backup Master Disc

It is most important to make a copy of the Master System/Utility disc provided with your DDI-1 and keep the original safe - it will be very costly to replace if damaged! Remember that the disc supplied has two sides, the System/Utilities side and the Dr LOGO side. Every disc, in fact, has two sides and you are free to use either side for any purposes.

Remember that if you are using a fresh disc to copy onto, the DISCCOPY and COPYDISC programs will format for you as well as doing the copying.
